Mumbai, Bollywood's hottest and most talked about pair Aishwarya Rai and Abhishek Bachchan were engaged Sunday.

Confirmation of this came from none other than Abhishek's father, film icon Amitabh Bachchan, at whose residence here the engagement took place.

There was no immediate word on the wedding date, industry sources said, adding Abhishek popped the question after the international premiere in Toronto Friday of Bollywood film "Guru" featuring the duo in the lead roles.

Speaking to reporters at Toronto, Aishwarya, a former Miss World, had pleaded with them not to jump to conclusions about her relationship with Abhishek, saying an announcement would be made at the appropriate time.

Aishwarya had in the past been romantically linked to actors Salman Khan and Vivek Oberoi. However, reports had been flying thick and fast for the past few months that she and Abhishek were about to tie the knot.

These reports gained added currency after Aishwarya accompanied Abhishek and his parents to perform rituals at a Varanasi temple in November 2006.
